yes there are several swimming requirements that must be passed during either indoc or during your freshman year should you not pass them.
if you've got swimming problems that they don't get fixed during indoc and you need extra help, please let me know. i'm a certified swimming instructor/ coach that can help you! don't neglect it!

Is2day, could you be more specific about the swimming tests? DS isn't a very strong swimmer, although he can certainly demonstrate the use of 2-4 strokes, swim for at least 100 yards (although probably using a combination of backstroke, sidestroke and a not very pretty crawl) and tread water for quite a long period of time.

Will that get him through? What else will he need? My husband is driving me nuts obsessing about this; hoping you can put his mind at ease.

if i remember correctly, the swimming tests involved a 200 yard swim, swimming nonstop for 40 minutes, treading, and so forth. basically if he's comfortable in the water he should be ok. if he needs to remediate that's fine.

He's an accomplished scuba diver (he has his certifications to be a master diver), and is an avid off-shore fisherman, so he's very comfortable in the water and in open ocean water, but he's never been interested in swimming for the enjoyment of swimming (as a small child he just wanted to learn to swim enough to be allowed to go out in the boat - that was the "carrot" that we used).

I'm trying to convince my husband that he'll be all right. Besides, it's a little late to be worrying about that now. I'd rather keep DS's confidence up.
